tcc-arm hosted on windows
Is there a short description of how to compile target ARM, host win32 on windows. Do not need float, just want to compile my vi-like editor and SLK parser generator for use on android. -- -- Thanks

libtcc1 example usage
Hi,
I am trying to use the example provided libtcc_test.c but with no luck. Compiles OK but I get the errors:
tcc: error: cannot find library: libtcc1.a
tcc: error: undefined symbol 'printf'
tcc: error: undefined symbol 'printf'
I've tried to hard code the lib_path, with -ltcc1 used in the makefile, no success. I'am using tcc version 0.9.26 (i386 Win32).
Any help will be greatly appreciated.
Thanks,
Lee

editing tccpe.c
Hello. I want change the default message of my compiled files from:
'This program cannot be run in DOS mode'
by:
'This program must be run under Win32'
I do it using this in line 499 of tccpe.c
},{
/* BYTE dosstub[0x40] */
/* 14 code bytes + "This program cannot be run in DOS mode.\r\r\n$" + 6 * 0x00 */
0x0e,0x1f,0xba,0x0e,0x00,0xb4,0x09,0xcd,0x21,0xb8,0x01,0x4c,0xcd,0x21,

},
but I want remove the last 11 0x00
I tried do it replacing dosstub[0x40] in line 237 by dosstub[0x35] and 0x00000080 by 0x00000075 in line 498. But I get bad result.
Please can someone help me please indicating the modifications needed for remove the last 0x00?
Carlos.

Relicensing TinyCC
Hi all, It has been discussed already on this list whether it would be good to relicense TinyCC under a more permissive BSD-like license. The discussion started here: http://lists.gnu.org/archive/html/tinycc-devel/2013-04/msg00052.html Opinions varied but mostly were positive so it appears to be worth to start the process and see how far we can get. For that purpose I've committed a new file RELICENSING with the suggested new license clause and a list for people to confirm their agreement (or disagreement). http://repo.or.cz/w/tinycc.git/commitdiff/e6704355000425e9 If you have contributed to TinyCC in the past, in particular if you are one of the copyright owners for an entire file, please add yourself to that file (rsp. replace the question mark) and then commit to the "mob" brancn with log message: Relicensing TinyCC Suggestions or concerns wrt. the procedure are welcome, also. Thanks, --- grischka

Missing predefs.h on x64 Linux?
Hiho,
--
----- stephan beal
http://wanderinghorse.net/home/stephan/
i just updated to "the latest" tcc:
[stephan <at> host:~/cvs/tinycc]$ git pull
...
From git://repo.or.cz/tinycc
...
And i am seeing what is probably a portability problem on x64 Ubuntu 12.04:
[stephan <at> host:~/cvs/fossil/cpdo]$ CC=tcc make
Generating dependencies...
+ tcc -Wall -Werror -fPIC -g -I. -I./include -I/home/stephan/include -UNDEBUG -DDEBUG=1 -DCPDO_ENABLE_SQLITE3=1 -DCPDO_ENABLE_SQLITE4=1 -DCPDO_ENABLE_MYSQL5=1 -c -o test.o test.c
In file included from test.c:25:
In file included from /usr/include/assert.h:37:
/usr/include/features.h:324: error: include file 'bits/predefs.h' not found
make: *** [test.o] Error 1
i haven't compiled this code with tcc in many months, so i cannot say when this started happening (and my git-fu is not powerful enough to figure it out :( ).
i get the same even if i disable assert by setting NDEBUG:
[stephan <at> host:~/cvs/fossil/cpdo]$ CC=tcc make DEBUG=0
+ tcc ... -UDEBUG -DNDEBUG=1 ...
In file included from /usr/include/assert.h:37:
/usr/include/features.h:324: error: include file 'bits/predefs.h' not found
make: *** [test.o] Error 1
Setting CC=gcc or CC=clang compiles as expected.
Any tips on working around this?

ARM hardfloat prolog
Hi Thomas,
I saw that you used the following line to store the floating point
arguments that have been passed in fpu register:
o(0xED2D0A00|nf); /* save s0-s15 on stack if needed */
In my 2nd edition ARM ARM this maps to the FSTMS instruction and there
is a note allowing implementations to keep the values in an internal
representation and just convert them to IEEE format for storing to
memory. So I don't think we can use this instruction to store double
arguments and need one FSTMS/FSTMD for each run of consecutive fpu
registers of same precision to be stored. Or have read otherwise?
Best regards,
Daniel

ABI compatibility
Hi, I've been trying to use TCC as an embedded C compiler (instead of using GCC and dlopen/LoadLibrary). I ran into a few ABI compatibility issues (on Linux (x86-64), Win32 and Win64), basically to do with the way TCC passes and returns structs/unions. It seems that TCC generally expects that structs are passed and returns on the stack or via pointers, and on these 3 platforms it is also possible that they will be packed into registers. Anyway, I've also been working on fixing these problems and Linux (x86-64) and Win32 appear to work (at least, they pass the tests I'm using). Anyway, I'm really just emailing to say hello and start towards hopefully getting this stuff merged in. James
